The regexp and non-regexp bugs and fixes are different.

The regexp "bug" was just us forgetting that regexp is provided by user
input, and should be validated.  The bug as reported by Ramsay was here
from the very beginning, i.e. commit 0e55991 (gitweb: Clearly distinguish
regexp / exact match searches, 2008-02-26), which was present in v1.5.1
if I have checked correctly.  The fix is about adding new code and should
apply cleanly to 'maint' and even to older versions; the only trouble
with older version might be whitespace issue related to refactoring
code into subroutines.

The non-regexp project search bug was using $searchtext instead of
$search_regexp as search regexp in gitweb.  The bug was present from
the very addition of project search, namely commit 0d1d154 (gitweb:
Support for simple project search form, 2008-10-03), which was present
in v1.5.1 if I have checked correctly.  Unfortunately the fix affects
code that was changed recently in a1e1b2d (gitweb: improve usability
of projects search form, 2012-01-31); I'll try to come up with equivalent
patch to 'maint' soon (if the current one does not apply, and I guess it
doesn't).
